Titanosaur, largest dinosaur ever, is discovered in Argentina

Researchers say they have made a discovery in Argentina of a dinosaur that would've been the largest animal ever to walk the earth.

The dinosaur would have been triple the size of a T-Rex weighing in at 77 tons.

Jose Luis Carballido of Argentina's Museo Paleontologico Egidio Feruglio told CNN the discovery is "Like two trucks with a trailer each, one in front of the other, and the weight of 14 elephants together."

The discovery was made near Patagonia, and palaeontologists told The Telegraph the find is thought to be a new species of titanosaur - a long-necked herbivore that lived in the Late Cretaceous period.
